I am using a treelist and dynamically create columns via a ngFor. There will always be a horizontal scrollbar as the treelist contents will always be wider than the screen. I notice that when my treelist has rendered and I use the horizontal scollbar, when scrolling to off screen content, the column headers and rows start to go out of alignment when almost at the end of scrolling. See below example. I think this is a bug in your treelist CSS. Can you comment?
